Embodiment 1
[0042] Example 1 Al-12Si-10Mg-1.3Fe-0.5Mn-0.5Cr-0.05Sr Alloy Heat Treatment
[0043] The raw materials used in this embodiment include Fe-rich aluminum alloys, pure aluminum, pure Mg, Al-20Si, Al-10Cr, Al-10Mn, and Al-10Sr master alloys. The forming method is as follows: according to the weight percentage first: Si: 12%, Mg: 10%, Fe: 1.3%, Mn: 0.5%, Cr: 0.5%, Sr: 0.05%, and the balance is Al. Among them, Fe is blended with Fe-rich recycled A356 aluminum alloy, and the insufficient amount of Al is blended with pure aluminum. Melt Fe-rich regenerated A356 aluminum, pure aluminum, Al-20Si, Al-10Sr alloy at 750°C, add weighed pure Mg to the melt when it melts to a semi-solid state, and manually Stir to make the ingredients uniform, heat up to 775°C, and keep warm for 10 minutes. Use 2# refining agent (chemical composition contains Na 2 SiF 6 , KCl, Na 3 AlF 6 and C 2 Cl 6 . ) for refining, let it stand for 5 minutes, keep the temperature of the molten metal at 775°C, remo...
Embodiment 2
[0047] Example 2 Al-10Si-12Mg-1.3Fe-0.6Mn-0.4Cr-0.05Sr Alloy Heat Treatment
[0048] The raw materials used in this embodiment include Fe-rich aluminum alloys, pure aluminum, pure Mg, Al-20Si, Al-10Cr, Al-10Mn, and Al-10Sr master alloys. The molding method is as follows: according to the weight percentage first: Si: 10%, Mg: 12%, Fe: 1.3%, Mn: 0.6%, Cr: 0.4%, Sr: 0.05%, and the balance is Al. Among them, Fe is blended with Fe-rich recycled A356 aluminum alloy, and the insufficient amount of Al is blended with pure aluminum. Melt Fe-rich regenerated A356 aluminum, pure aluminum, Al-20Si, Al-10Sr alloy at 750°C, add weighed pure Mg to the melt when it melts to a semi-solid state, and manually Stir to make the ingredients uniform, raise the temperature to 770°C, and keep it warm for 20 minutes. Refining with refining agent, standing still for 5 minutes, keeping the temperature of molten metal at 770°C, pouring into a metal mold preheated to 190°C after removing slag, and solidi...
Embodiment 3
[0052] Example 3 Al-12Si-10Mg-1.6Fe-0.4Mn-0.6Cr-0.1Sr Alloy Heat Treatment State
[0053] The raw materials used in this embodiment include Fe-rich recycled aluminum alloys, pure aluminum, pure Mg, Al-20Si, Al-10Cr, Al-10Mn, and Al-10Sr master alloys. The forming method is as follows: according to the weight percentage first: Si: 12%, Mg: 10%, Fe: 1.6%, Mn: 0.6%, Cr: 0.4%, Sr: 0.1%, and the balance is Al. Among them, Fe is blended with Fe-rich recycled A356 aluminum alloy, and the insufficient amount of Al is blended with pure aluminum. Melt Fe-rich regenerated A356 aluminum, pure aluminum, Al-20Si, Al-10Sr alloy at 750°C, add weighed pure Mg to the melt when it melts to a semi-solid state, and manually Stir to make the ingredients uniform, heat up to 780°C, and keep warm for 20 minutes. Refining with refining agent, standing for 5 minutes, keeping the temperature of molten metal at 780°C, removing slag, pouring into a metal mold preheated to 210°C, and solidifying under vib...
